Frequently Asked Questions - AX-MLOC740 Axxess

What is the Axxess AX-MLOC740 used for?

The Axxess AX-MLOC740 is a digital signal processor and line output converter that allows you to connect an aftermarket amplifier to a factory stereo without losing any sound quality.

How do I install the AX-MLOC740?

Connect the high-level speaker inputs from your factory system to the device's input harness. Then run the low-level RCA outputs to your amplifier. Connect the remote turn-on wire and ground properly.

Does the AX-MLOC740 require external power?

Yes, it needs a 12V DC power supply from the vehicle’s electrical system and a good ground connection to function.

Can I use the AX-MLOC740 with any factory radio?

It is compatible with most factory radios that have high-level speaker outputs. It can handle up to 40V peak-to-peak input signals.

How do I adjust the input sensitivity?

Use the small screwdriver-adjustable gain knob on the device. Turn it until the output to your amplifier is clean and without distortion.

Does the AX-MLOC740 have any filtering?

Yes, it includes noise filtering to eliminate alternator whine and other interference, ensuring a clean audio signal.

What is the maximum output voltage?

The maximum output voltage is 5V RMS, which is standard for most aftermarket amplifiers.

Is the AX-MLOC740 waterproof?

No, it is not waterproof. It should be installed in a dry location inside the vehicle, away from moisture.

Can I use the AX-MLOC740 without a remote turn-on wire?

It has automatic remote turn-on sensing, so it can detect the audio signal and turn on without a dedicated remote wire. However, using a remote wire is recommended for best performance.

Where can I find the manual for the AX-MLOC740?

The user manual is available for free download on notice-facile.com in PDF format.

USER MANUAL AX-MLOC740 Axxess

Installation Instructions

The Line Output Converter (LOC) should be installed on a stereo's speaker output wires or the output wires on an OEM amplifier of up to 80 watts per channel. These wires can be found behind the stereo in the dash, on the outside of an OEM amplifier, or on the input terminals on the OEM speakers.

Wire color and function

The audio input wire colors are an EIA standard for car stereo applications as follows:

Input harness

White = left front (+) input White/Black = left front (-) input Gray = right front + input Gray/Black = right front (-) input Green = left rear (+) input Green/Black = left rear (-) input Purple = right rear (+) input Purple/Black = right rear (-) input

Power harness

Yellow = battery +12v input Black = power (-) ground input Blue = remote +12v output Brown = reference ground (-)

Note: Be sure that all audio input connections are polarized or in phase with each other. That is, the positive output wires from the audio source need to be connected to the corresponding positive input wires of the LOC. The same goes for the negative audio wires. Failure to do this will result in poor bass response and low quality audio.

The LOC is designed to convert (4) channels of speaker level audio into (4) channels of line level audio. This allows for the installation of line level products such as amplifiers, EQs and crossovers on systems that do not have RCA line level outputs. In addition this device will also detect the presence of an audio signal and then generate a +12V output that can be used to turn-on an aftermarket amplifier.

Features

80 watts maximum input

Input circuit corrects

Crossover distortion commonly found on other brands of LOCs

6:1 Step down with variable output

Gold flashed RCAs

Attractive and durable enclosure

Note: The LOC will shut off 60 seconds after no signal detected.
